- Q:Why should the use of high pressure perfusion waterproof plugging method
- High pressure grouting construction principle: is a special high-pressure grouting waterproof material through the high-pressure infusion equipment into the concrete crack structure extended until all the cracks (including the naked eye is difficult to meet) filled with water (water) with the cross-linking reaction, Release a large number of carbon dioxide gas, resulting in secondary pressure, high pressure and secondary pressure will be pressed into the elastomer and filled with all the gaps, to stop the purpose of leakage, it can be said that the best performance of plugging material,
- Q:What material waterproofing can be mixed with cement sand
- Construction can be made with the waterproofing agent and cement made of waterproof mortar. The ratio of cement to sand is 2: 3, and the amount of waterproofing agent is 1% of the cement.
- Q:Rigid (concrete) waterproof roofing shop SBS coil can brush a layer of waterproof paint before?
- First, rigid (concrete) waterproof roofing SBS membrane should not be painted before the coating of any waterproof coating, otherwise it will damage the bonding strength of the coil and the grassroots.
- Q:Waterproof mortar expensive or dry mortar expensive
- Dry mortar is usually called hydraulic cement mixed mortar, refers to the dry sieve treatment of aggregate (such as quartz sand), inorganic cementing materials (such as cement) and additives (such as polymers) and so on a certain proportion of physical mixing Into a granular or powdered, in the form of bags or bulk transported to the site, add water, mix directly after the use of materials.
- Q:What should you pay attention to before the construction of the basement waterproofing membrane?
- 3, painting the bottom line: for the reasonable arrangement of the daily pavement workload, must first on the basis of the program according to set the program to draw a good dividing line, the entire track and field into pieces, and then press the block by pavement. In order to ensure smooth drainage and less joints and other requirements, the use of the first outer ring after the construction process.
- Q:What decoration materials, light and water, and the wall, the perfect combination of glass
- Second, cover the surrounding surface
With the tape or the US profile of paper to cover the surface of the interface surface, according to the width of the gap to keep the gap width, width uniformity to ensure that the sealing of the work lines neat and perfect;
- Q:Finished house bathroom waterproof household acceptance should be how to accept?
- 3: waterproof cement mortar leveling layer and foundation with dense, no hollowing, smooth surface, no cracks, from the sand, yin and yang angle made of circular arc.
- Q:What is the difference between finished mortar and cement mortar?
- Finished mortar for dry areas, because the addition of lime, lime water retention is good; cement mortar for wet areas, because the high strength.
- Q:How can the toilet waterproof works fail?
- After the failure of the bathroom waterproofing project to solve the specific needs of the specific analysis of targeted treatment.
Bathroom waterproof is the problem more decoration works. The main reasons are: 1, construction (local, details, etc.); 2, waterproof material problems; 3, the structure (such as uneven settlement, cracking, etc.); 4, to save a little waterproof waterproof measures.
After the three must be redo waterproof, the first type of reasons can be used to the appropriate remedial measures, pay the table "bathroom waterproof failure part of the phenomenon and the remedy list."
Please responsible professionals in the field to carefully check the judge to find specific reasons for dealing with the need to destroy the red or must be destroyed, do not affect others after causing greater losses. The following are the same as the "
- Q:Find the construction steps for waterproof coatings
- 3, note
(1) rain weather and five wind above the weather shall not be construction.
(2) coating waterproof layer shall not have bottom leakage, cracking, holes and other defects and peeling, bubbling, carcassing and wrinkle phenomenon. Coating waterproof layer and the base should be bonded between the solid, no hollowing, trachoma, delamination and so on.
(3) the coating site should be continuous, solid, shall not appear Alice, hollowing parts.
(4) rigid protective layer before the completion of any personnel shall not enter the construction site, so as not to damage the waterproof layer; coating of the overlapping parts should be care by the staff.
(5) roof should be used lime soil, clay or sub-clay for backfill, thickness 50 cm, backfill shall not contain stones, gravel, ash and organic matter. Artificial compaction of each layer 25 cm, mechanical compaction of each layer 30 cm, rammed to prevent damage to the waterproof layer. In the backfill thickness of more than 50 cm, it is allowed to use mechanical backfill rolling.
